We have an original Eichler master bathroom sink available. It is cast-iron, rectangular sink with a metal rim, with rounded edges, appr. 21” wide and 19” deep. It is almost 50 years old and not in perfect state (the porcelain coating has some rust stains around the drain), but not too bad. Faucet still attached. Free to a good home.
